Hardware Overview Main neoVI and ValueCAN hardware from Intrepid Control Systems offer a way to interface your PC to a variety of different networks commonly used in today's vehicles. Using neoVI or ValueCAN devices, you can monitor a number of different networks simultaneously. Most neoVI devices connect to the vehicle through a 25 pin DSUB connector while ValueCAN devices connect through a 9 pin DSUB connector. neoVI and ValueCAN devices can simultaneously read and transmit messages on all of its connected networks, time-stamp events, and transfer the messages to the PC. Hardware configuration can be done in Vehicle Spy or through the use of a hardware explorer. The hardware explorers allows you to setup baud rates, enable/disable networks and control device behavior.

28 / 71 Intrepid Hardware Help J1850 PWM (Ford PWM)

J1850 PWM (Ford SCP) - neoVI Main

Applies to neoVI Blue To implement J1850 PWM communications neoVI uses the Ford SCP LBCC communications IC with the Ford specified physical layer. It optionally lets you monitor the entire network using special monitor mode firmware. The LBCC IC allows you to setup a number of parameters that control its operation. When enabled, the neoVI Firmware supplies monitor mode and the LBCC provides transmit operations. First, you can set the bit rate of the SCP network (figure 1 : bubble 1). The standard network bit rate is 41.6 kbps. The higher speed 83.3 kbps is sometimes used on the network for special network operations. Special Monitor mode only supports the 41.6 kbps rate. The OBD connector used in neoVI connects the J1850 VPW network to the J1850 + line. neoVI contains a relay the can switch the JPWM + signal on to that line instead of JVPW. This allows you to use one connector with both protocols. You can have neoVI default to either connecting VPW (default) or PWM (Figure 1: bubble 2). You can control the relay at run time using a neoVI virtual network can message. You can set the Node Address of the Ford SCP node. This is shown in the figure 1: bubble 3. This is used for setting the source id and is used when the LBCC generates In frame responses (IFRs). This address must be unique for each node on the SCP network. Next, you can set the Network Driver and Receive Control Register (NDRC) of the LBCC. This is shown in figure 1 bubble 4. The NDRC is a register in the LBCC which allows you to transmit or receive on portions of the dual wire network. Normally, these should all be checked. The LBCC allows you to optionally handle two function read data message parameters. These are setup in figure 1 : bubble 5. If you want to handle a function read data message, check the number 1 or 2 and enter the function code. These settings are entered in Lookup Table 2 of the LBCC device. You can set the actual data for the function code with the "LBCC Set FRead data" neoVI virtual network command. You can setup the LBCC look up table 1 (figure 2). Lookup table 1 controls what functional messages the LBCC should receive. You can have up to 31 entries in this table. In figure 2, we setup the LBCC to receive three functional messages including 0x1E, 0xF1, and 0x22. Blank spaces in the table are ignored. Special Monitor mode allows you to monitor all traffic on the SCP network. To enable this node click the check box in figure 1 bubble 6. This enables special firmware in neoVI that monitors and decodes the raw SCP waveform. When this is done, both J1850 VPW and ISO/KW2k protocols are disabled. You can still use the Ford LBCC channel. All monitor mode messages come across on the J1850VPW network. Node Address - The SCP Node address is used for three purposes. First, the node address is the third byte of every transmitted message (the source address). Next, the address is used for node address acknowledgement. Finally, it is used to determine which physically addressed SCP messages should be received. Tx Driver Enable -These two bits enable network drivers A (bus -) and b (bus +). When set, each bit will enable the corresponding output pin driver. When the bit is clear the pin is tristated. Rx Enable Bits - These three bits control the inputs into the LBCC bit decoder. The receivers are enabled when the bits are a "1". Disabled receivers force a "stuck active" condition to the bit decoders.

UART/ISO9141/KW2K/LIN - neoVI Main

Applies to neoVI Blue, neoVI Red, neoVI FIRE, and neoVI Yellow The neoVI supports a UART/ISO9141/Keyword 2000/LIN network. This network is basically a UART/SCI unit with a hardware level shifter (Figure 1). There are many variants of a UART network schemes which can be monitored with this network. As shown in figure 1, the network has a pull up voltage for the K and L line of VBATT. In neoVI Blue, the pull up resistor can also be changed. Please see the Hardware Settings topic for more information on changing these items. Please note that the factory default pull up voltage is VBATT with a pull up resistor of 510 ohms.

Figure 1 - neoVI implements a hardware level shifter for each K and L line. As shown in figure 2, there are many settings you can adjust for your UART network. These options are discussed in the following topics: Timing/Baud Rate, Initialization, and Error Checking.

UART Timing - neoVI Main Applies to neoVI Blue, neoVI Red, neoVI FIRE, and neoVI Yellow The UART network supports software programmable timing parameters. These include the baud rate and time delimiters as described in the ISO9141/Keyword 2000 specs. First, you can setup a baud rate. Intrepid Hardware Explorer provides you with many common UART speeds present in Vehicle Networks to choose from. In normal UART operations timing delimiters specify how messaging takes place. These settings are shown in Figure 2 below. The settings are explained in table 1 below.

Figure 1 - You can setup a baud rate for UART communications.

Figure 2 - The timing specifications used in ISO communications for message delineation. Table 1 - Descriptions of timing parameters in ISO/UART

Timing Parameter Parameter Name Description neoVI determines when a message ends using this parameter. If no data byte has been Rx Inner Frame Spacing Receive Inter-frame Separation received within this period the end of message is signaled. Tx Inner Frame Spacing Transmit Inter-frame Separation This is the delay the transmitter will wait between two message transmissions. Tx Inter byte Spacing Transmit Inter-byte Separation This is the delay that neoVI uses between each transmit byte.

The Message Termination section allows you to choose how frames are spaced. Select Inner Frame Time for ISO9141 or Keyword 2000 networks. For GME CIM-SCL networks select GME CIM-SCL.

34 / 71 Intrepid Hardware Help Initialization Waveforms

UART Initialization Waveforms - neoVI Main Applies to neoVI Blue, neoVI Red, neoVI FIRE, and neoVI Yellow Some UART standards such as Keyword 2000 and ISO9141 require you to initialize an ECU before attempting to send messages to it. Usually this initialization involves signaling on either or both of the K and L line. You can select the initialization from the Init table section of the ISO9141/KeyWord 2000/K-Line section of the hardware Explorer (figure 1)

Figure 1 - Init table option in hardware explorer. You can cause a initialization to occur on the network by clicking the Init column in Vehicle Spy or setting the init flag in the status bit-field in the message you send via the DLL. The message can have no data bytes (for five baud initialization for example). neoVI supports the standard initializations like Fast Init and Five Baud. Also, neoVI also offers a custom initialization because there has been a variety of initialization implementations. For custom initializations you can have a 16 step waveform. This is defined in the custom initialization table in hardware explorer. Each step can last up to 32.767 seconds and can control both the K and the L line.

Figure 2 - You can select the init type from the drop down list in neoVI explorer. Table 1 - Initialization options in Vehicle Spy

Initialization Description Fast Init A 25 ms low on the K line followed by a 25 ms high followed by the start communication message Five Baud Address 0x55 transmitted at 5 Baud (0.125 ms / bit) Custom Waveform is user defined by a sixteen entry table

35 / 71 Intrepid Hardware Help Error Checking

UART Error Checking - neoVI Main

Applies to neoVI Blue, neoVI Red, neoVI FIRE, and neoVI Yellow The ISO9141 and Keyword 2000 protocols use a checksum field to protect the data that is transmitted. neoVI allows you to disable the automatic addition of this checksum to transmitted messages and the checking of it on the reception of messages. This maybe useful for a UART protocol that doesn't use the checksum or calculates it differently. A parity setting is also available if your network requires this.

Figure 1 - The standard checksum for ISO communications can be disabled. Parity can also be added if needed.

36 / 71 Intrepid Hardware Help Local Interconnect Network (LIN)

LIN : Local Interconnect Network - neoVI Main Applies to neoVI Blue, neoVI Red, neoVI FIRE, and neoVI Yellow neoVI supports communication on LIN (Local Interconnect Network). Once detecting a proper Sync Break and Sync field, the neoVI will wait for the Msg Identifier field. The message reception will begin with the Msg ID field. The neoVI will receive the entire message according to the LIN spec. After receiving the message error free, the neoVI will send the received message to the host starting with the Msg ID field. If there are any errors neoVI will report the errors back to the host. Table 1 below lists the errors checked for by the neoVI device. neoVI supports acting as a monitor, master, and slave. Enabling LIN is done in the Hardware Explorer. For neoVI Blue LIN is enabled under the ISO9141/KWord 2K/UART/LIN options. Set the Mode to "LIN Mode" and the "Rx Transceiver" to LIN. Also make sure the baud rate is correct for your network (Figure 1).

Figure 1 -LIN mode is entered via the neoVI Explorer. To Enable LIN on a neoVI FIRE, neoVI Red, and neoVI Yellow is done in Hardware Explorer by Selecting the channel under network Enables and then setting the proper baud rate for that LIN channel (Figure 2)

Figure 2 -LIN mode is enabled via the neoVI 3G Explorer.

LIN Slave Table - neoVI Main Applies to neoVI Blue, neoVI Red, neoVI FIRE, and neoVI Yellow LIN Slave messages sent to the hardware are stored in the hardware's internal slave table until it is requested by a master message request. Data in the internal Slave Table can updated by resending the slave message in your software application. When a master request is received by the hardware, the latest data for that ID in the LIN Slave table will be sent.

This section also contains the neoVI theory of operation. The hardware features discussed in this section include the following: 1) neoVI LED 2) General Purpose IO 3) DAQ Pacer Clock 4) Specifications 5) Hardware Settings

40 / 71 Intrepid Hardware Help Theory of Operation

Theory of Operation - neoVI Main Applies to neoVI Blue This section details the theory-of-operation of the neoVI device. A block diagram of the device is shown in figure 1 below. The neoVI device consists of three independent µControllers which have a total of 20 MIPS (millions of instructions per second) of processing power. This processing power can read messages from 9 independent networks. After reading the messages the neoVI can do one or all of the following things: 1) send them to the PC via RS232 or USB, 2) process the message, or 3) store the message in onboard storage. The functionality of the neoVI is based on its firmware. All three of the µControllers in the neoVI device have field upgradeable firmware. This means the neoVI device can be updated with new functionality at anytime in the future. The following topics explain the diagram further: 1) Main 51 µController, 2) Main PIC µController, 3) CAN Networks, 4) LBCC Protocol IC, and 5) ISO/J PIC µController section.

Figure 1 - the neoVI block diagram (click for larger image)

Main 51 µController The Main 51 µController (figure 2) is responsible for collecting messages from the Main PIC µController and processing them. Normally, when neoVI is used as a PC interface this means sending them to the PC via USB or RS232. It also could store the messages on it's MMC (multimedia card storage device). It could also process the messages and do something such as transmit a response or change a general purpose IO bit. The RS232 port is capable of 115.2 kb, 57.6 kb, 38.4 kb, 28.8 kb, 19.2 kb, 9600 bps, and 4800 bps baud rates. It includes RS232 control lines for hardware handshaking (RTS/CTS) and DTR acting as a DCE (Data Communication Equipment) device. The USB port supports USB 1.1 full speed 12 Mega-Bits per second. The device is software programmable to use either Bulk only or Isochronous in/bulk out transfers. The neoVI device defaults to 56k Baud RS232 communication on power up. The communication can then be changed by the host software by sending commands on USB or RS232.

Figure 2 - The Main 51 µController

Main PIC µController

41 / 71 Intrepid Hardware Help Theory of Operation

The Main PIC µController is the heart of the Vehicle network functions. Its job is to read network messages from the specific subsections, timestamp them and send them to the Main 51 µController. The Main PIC µController is directly responsible for the MISC 1 and MISC 2 signals, the J1708 protocol, and configuration of the LBCC and CAN controllers. As the owner of the timestamp clock, the Main PIC generates the timestamp clock for the DAQ pacer functionality. It also owns the trigger signals for J1708, Ford SCP (LBCC), and all of the CAN networks. The Main PIC µController is protected by a internal watchdog timer and controls the reset lines for all of the other circuits.

Figure 3 - The Main PIC µController

CAN Networks neoVI has four independent CAN networks. The CAN protocol IC is the MCP2510 IC from Microchip Technology. Each protocol chip, is connected to the appropriate physical layer for that CAN network. All status and control signals for each physical layer are mapped to internal µController pins. This allows complete software control of the CAN functionality.

Figure 4 - The neoVI CAN Networks

LBCC Protocol IC The LBCC protocol is a protocol IC from Visteon which performs the J1850 PWM Ford SCP protocol. It supports a programmable function id table with 31 locations, a programmable network address, and two programmable function read data registers.

Figure 5- The neoVI LBCC interface

ISO/J PIC µController Section The ISO/J PIC µController main functionality is to generate the J1850 VPW and ISO/UART protocols. Other responsibilities include the following: 1) LED Control, 2) Real-Time Clock Interfacing, 3) On-board Temperature Sensor 42 / 71 Intrepid Hardware Help Theory of Operation

Interfacing, and 4) MISC signals 3 through 7. The J1850 VPW software is software controlled peripheral based VPW generation. This means that the ISO/J PIC µController uses a timing peripheral to generate and receive variable pulse width (VPW) waveforms. This allows the neoVI device to create faults and analyze VPW waveforms that would not be possible with other protocol ICs. It also allows support of different in-frame responses which cause incompatibilities between J1850 VPW protocol ICs. The ISO/UART section is very flexible. The K and L lines have software controlled transmit enable lines allowing many different variants of UART or ISO9141 communications including: Tx on L Rx on K; Tx and Rx on K; Tx on K and L and Rx on K. The MISC signals contain four 10 bit analog inputs and one external wake-up input.

43 / 71 Intrepid Hardware Help LED

LED - neoVI Main Applies to neoVI Blue The behavior of the neoVI LED is programmable. The LED can be setup to activate on network activity, display the state of a MISC pin, or change state according to a script. You can setup this behavior in the neoVI Explorer. The LED Operating Mode selection (figure 1 : bubble 1) sets the behavior. The LED settings are listed in Table 1 below. For settings that cause the LED to flash the neoVI provides two additional settings. The first setting is the flash type. You can either have the LED turn green and then turn off or flash green and resume red flashing. The second setting is the flash duration. This is the time the green element is active for each flash. The LED can also be controlled through the neoVI Device virtual network.

Figure 1 - How the neoVI LED works can be set in neoVI explorer. Table 1 - The LED Operating Modes

LED Operating Mode Description The standard LED setting. This setting will cause the LED to toggle between Red and off every 104 ms. You can Standard Mode also control the LED with scripts using this setting. Display MISC3 Displays the state of the MISC3 pin. It will display green if the pin is on otherwise it will be off. Display MISC4 Displays the state of the MISC4 pin. It will display green if the pin is on otherwise it will be off. Display MISC5 Displays the state of the MISC5 pin. It will display green if the pin is on otherwise it will be off. Display MISC6 Displays the state of the MISC6 pin. It will display green if the pin is on otherwise it will be off. Display MISC7 Displays the state of the MISC7 pin. It will display green if the pin is on otherwise it will be off.

44 / 71 Intrepid Hardware Help General Purpose IO

General Purpose IO Main

Applies to neoVI Blue Overview neoVI has six general purpose 5 VDC IO pins. These are labeled as MISC signals on the neoVI connector. These pins can be used for controlling or monitoring external devices. Basic Setup The general purpose IO are setup in the neoVI explorer. The general IO tree node is shown in figure 1. On the panel you can setup the direction, type, and initial state of each IO pin. Each MISC signal has a drop down box (figure 1 : bubble 1). In this drop down box you can set if the MISC pin is an input, output initially off, or an output initially on. The outputs are capable of LED drive through a current limiting resistor. The maximum current of all outputs should not exceed 50 mA. For protection, each IO pin has a series 100 ohm resistor and a transient protection device. Analog Inputs If setup as input, MISC pins 3 through 6 can be setup as analog inputs. You can setup analog inputs via the "Analog Setting" drop down (figure 1 : bubble 2). The settings are : 1) no analog inputs, 2) analog input on MISC 3, and 3) analog inputs on MISC 3-6. When setting up MISC3 only, the sampling rate will be once per millisecond. If the setting is for MISC3-6, the sample rate will be every four milliseconds. General IO Reporting You can setup the general IO to be automatically reported to the host in neoVI explorer (figure 2). You can setup the general IO to be reported at an interval or based on digital inputs changing (figure 2 : bubble 1). The report will be sent to the host as a neoVI Device Virtual Network message. When reporting based on interval is selected you can select the interval from the drop down box shown in bubble 2 in figure 2. You can select an interval from 1 to 125 ms. If you selected a report based on digital change, you can select both an interval the inputs are tested (figure 2 : bubble 2) and which digital inputs to test (figure 2 : bubble 3). You can select as many as are listed. The report based on digital change will "de-bounce" the reading by testing the inputs twice. Each test will occur at one-half the time interval.

46 / 71 Intrepid Hardware Help DAQ Pacer Clock

DAQ Pacer Clock - neoVI Main Applies to neoVI Blue Overview The neoVI device can generate a clock (figure 1) on the MISC2 pin that can be used to correlate data collected with the neoVI device with other data acquisition equipment that accepts an external clock. The clock rate is programmable between 1.25 Khz and 2.5 Mhz (See table 1 for frequencies). The neoVI devices timestamps the exact start time of the pulses. This start timestamp provides a marker to compare data from the DAQ board and the neoVI. How to use it The following list of steps shows how to use this feature: Step 1 : Wire the MISC 2 signal to the DAQ card external clock input Step 2 : Setup the MISC 2 Signal as a digital output in neoVI explorer Step 3 : Start Monitoring the network Step 4 : Start the DAQ Card Data Acquisition for an external clock with the desired number of samples Step 5 : Send the Start DAQ neoVI Device Virtual Network Command to start the clock. neoVI will send a neoVI Device Network message time-stamped when the DAQ Clock was started. Step 6 : Record network messages from the neoVI until the DAQ card has acquired the proper number of samples Step 7 : After the DAQ Card completes its scan, assemble the DAQ card data and neoVI message buffer in to one buffer using the start timestamp. Analyze, display or store your results. Step 8 : Send the Stop DAQ neoVI Device Virtual Network Command to stop the DAQ Clock.

59 / 71 Intrepid Hardware Help General Purpose IO

General Purpose IO Main Applies to neoVI Yellow Overview neoVI Yellow has three general purpose 3.3 VDC IO pins. These are labeled as MISC signals on the neoVI connector. These pins can be used for controlling or monitoring external devices. Basic Setup The MISC IO are setup in the neoVI 3G Explorer. Figure 1 shows the input output configuration. This is done by selecting Initial Values under MISC IO from the tree. On the panel shown, you can setup the direction, type, and initial state of each IO pin. The outputs are capable of LED drive through a current limiting resistor. The maximum current of all outputs should not exceed 5 mA. For protection, each IO pin has a series 47 ohm resistor and a transient protection device. Analog Inputs MISC pins through 3 can be setup as analog inputs. To enable an analog input, you can select "Analog inputs" from the "Initial Setup" window. General IO Reporting You can setup the general IO to be automatically reported to the host in neoVI 3G Explorer (figure 2). You can setup the general IO to be reported at an interval or based on digital inputs changing (figure 2 : bubble 1). The report will be sent to the host as a neoVI Device Virtual Network message. When reporting based on interval is selected you can select the interval from the drop down box shown in bubble 2 in figure 2. You can select an interval from 1 to 125 ms. If you selected a report based on digital change, you can select both an interval the inputs are tested (figure 2 : bubble 2) and which digital inputs to test (figure 2 : bubble 3). You can select as many as are listed.

Figure 1 - neoVI MISC pins can be setup as digital outputs, digital inputs or analog inputs.
